Formation

Formation

The banded iron layers are formed in sea water when oxygen is released by photosynthetic cyano-bacteria. The oxygen then combines with dissolved iron in ocean to form insoluble iron oxides, which precipitated out, forming a thin layer of banded iron formation on ocean floor.
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Banded iron formation vs Latite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Banded iron formation and Latite Reserves. Banded iron formation are distinctive units of sedimentary rock that are almost always of Precambrian age. Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Banded iron formation vs Latite information and Banded iron formation vs Latite characteristics in the upcoming sections.

Banded iron formation vs Latite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Banded iron formation vs Latite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Banded iron formation and Properties of Latite. Learn more about Banded iron formation vs Latite in the next section. The interior uses of Banded iron formation include Decorative aggregates and Homes whereas the interior uses of Latite include Decorative aggregates, Entryways and Interior decoration. Due to some exceptional properties of Banded iron formation and Latite, they have various applications in construction industry. The uses of Banded iron formation in construction industry include As dimension stone, Used for flooring, stair treads, borders and window sills. and that of Latite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.

More about Banded iron formation and Latite

Here you can know more about Banded iron formation and Latite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Banded iron formation and Latite consists of mineral content and compound content. The mineral content of Banded iron formation includes Hematite, Magnetite, Quartz and mineral content of Latite includes Alkali feldspar, Biotite, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Banded iron formation vs Latite, the texture, color and appearance plays an important role in determining the type of rock. Banded iron formation is available in red, reddish brown colors whereas, Latite is available in black, brown, green, grey, pink, white colors. Appearance of Banded iron formation is Layered, Banded, Veined and Shiny and that of Latite is Rough. Properties of rock is another aspect for Banded iron formation vs Latite. The hardness of Banded iron formation is 5.5-6 and that of Latite is 5-5.5. The types of Banded iron formation are Algoma-type , Lake Superior-type, Superior-type and Taconite whereas types of Latite are Rhomb porphyries. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Banded iron formation and Latite is white. The specific heat capacity of Banded iron formation is 3.20 kJ/Kg K and that of Latite is 0.92 kJ/Kg K.
